{"product_id":"wilwood-160-8136","title":"Wilwood Scalloped Ultralite Rotor, 12.19 x 0.81 Inches, Light Dirt Racing","description":"\u003cp\u003eThe 12.19-inch version of the scalloped Ultralite ring provides a larger pad sweep while retaining a 0.81-inch section. Its 32-vane iron construction and plain faces are intended for light dirt racing, not general-purpose road braking. Since its founding by Bill Wood in 1977, Wilwood has designed and manufactured disc brake systems from its base in Camarillo, California. Its products span rotors, calipers, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. Brake selection should account for the whole installation, including mounting dimensions, friction materials and hydraulic balance.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 160-8136\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e One rotor; not an axle pair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside diameter:\u003c\/strong\u003e 12.19 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal thickness:\u003c\/strong\u003e 0.81 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor material:\u003c\/strong\u003e Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e 32 vanes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriction surface:\u003c\/strong\u003e Plain Face\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Plain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximate weight:\u003c\/strong\u003e 5.90 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory burnished:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDynamically balanced:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation orientation:\u003c\/strong\u003e Non-directional\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor attachment pattern:\u003c\/strong\u003e 8 x 7.00 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor mounting hole \/ thread:\u003c\/strong\u003e 0.326 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegistration \/ lug inside diameter:\u003c\/strong\u003e 6.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFar-side inside diameter:\u003c\/strong\u003e 8.56 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntended use and restrictions:\u003c\/strong\u003e For light dirt racing.
